STOVE-PIPE COLLAR AND CLAMP.

QPECIPICATION forming part of Letters Patent No. 346,188, dated July 27,1886.

Application filed September 1, 1385. Serial No. 175.920.

T 0 all whont it may concern.-

Be it known that we, EMMETT II. BROWER and JOHN J. TRAVIS, both ofCarson City, in

' the county of Montcalm and State of Michigan,

haveinvented a new and Improved Stove-Pipe Collar and Olamp, of whichthe following is a full, clear, and exact description.

Our invention relates to collars and clamps for holding stovepipes inthe holes of chimney-flues, and has forits objects to hold the pipesecurely in the collar, and so as to prevent forcing the pipe back toofar into the flue, and also to prevent the pipe from slipping forwardout of the collar, and to hold the collar securely to the chimney-wall,and also to prevent soiling of the wall-finish by soot or dust when thepipe is removed from the line for any purpose.

The invention consists in certain novel features of construction andcombinations of parts of the stove-pipe collar and clamps, all ashereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is an outside face view of our improved stove-pipe collar andclamp, with the nut of the collar-clamp removed. Fig. 2 is a sectionalView of the collar and clamp on the line m, Fig. 1, and as attached tothe front wall of a chimney or fire-place. Fig. 3 is a sectional view ofthe same on the line y y, Fig. 1. Fig. 4 is a detail inner face view ofthe upper part of the collar, parts being broken away and shown insection; and Fig. 5 is a detail perspective view of one arm of theclamp-bar.

The letter A indicates the stove-pipe collar, which is round in generalform, and has annular stiffeningcorrugations. Atits lower part, and forabout one-half way around, at a short distance back from its centralopening the collar is formed with an inwardly-projecting flange, B, theinner edge of which, together with the outer edge of the collar, restsagainst the face of the chimney-wall O, as in Fig. 2.

In the face of the collar A, at diametricallyopposite points, are formedthe notches a a, at the base of which notches in the face of the collarare formed the recesses act, into which notches the ends (Z d of theopposite side parts, d d, of the bowed clamp-bar D are adapted to enter.The clamp-bar D is made in U form,

(No model.)

its crossbar is widened toward the center, and at its center, on oneside, is formed the swell d, and in the opposite side is formed therecess d, at the sides of which recess are formed the outwardly andupwardly projecting lugs (7. The ends of the arms (1 are flattened toenter the notches a of the collar, and are provided with the side lugs,a, which fit in the recesses a in the face of the collar, whereby theends of the arms (1 are llush with the said face.

Across the stove-pipe hole 0 in the wall 0 is placed, by its ends e cresting against the back of said wall, the bar E, which has fixed to itthe bolt end F, which passes through the recess d of the cross-piece ofthe bar D, and receives a nut, G, which, when screwed tightly to thecrosspicce, will hold the bar E to the back of the wall (I, and willdraw the lugs to" a on the ends (I d of the bar D hard into the recessesa a of the collar A, and thereby bind said collar firmly to the outerface of the wall, as in Fig. 2, and centrally around the stove-pipe hole0. The bolt F is held in the recess d" by the back of the said recess,and by the nut G, resting against the lugs (7 and keeps the collar-clampbars D E in proper relative positions. The nut G is removed from bolt Fin Fig. 1, to show the boltreccss and lugs to better advantage.

Directly opposite the semicircular or inturncd flange B of the collar isplaced the curved Stovepipe-clamp plate H, which extends about half-wayaround the inner margin of the opening of the collar A, and at the innerface of said collar, and at its central part, it is provided with aflange, I, which projects beneath the inner edge of the collar A, andpreferably through a notch, 2', formed in the collar, and thence upwardat the outer face of the collar. On the inner face of the collar A areformed the long lugs J, corresponding with recesses t", formed in theinner face of the flange I, said lugs J and recesses 6 serving to steadyand guide the clampplate II, so that said plate will be forced downfairly on the top of a stove-pipe placed within the collar A by a screw,K, passing through the collar A. Another object ofthe flange I, lugsJ,'and recesses t is to prevent detachment of the clamp-plate II fromthe collar A when the stove-pipe is removed from beneath theclamp-plate, as these parts are intended to fit snugly together. The

screw K is threaded through the collar A, or

a lug, 7c, thereon, and is turned down onto the top of the clamp-plateH, or onto a lug, h, fixed thereto, said lug h preferably having arecessto receive the end of the screw, as best seen in the wall, andstay-wires for securing thepipe in place are unnecessary.

. Another advantage ofonr device is, that there is nothing at the backof the wall 0 which can interfere with the cleaning of the chimney-flue,as the clamp-bar E offers little or no obstruction to the passage of thebrush, and the stovepipe and its collar and clamp need not then beremoved.

A further advantage of our collar is, that the flange B at its lowerpart prevents the escape of soot or dust onto the outer face of thechimney-wall 0 when the Stovepipe is withdrawn from the hole 0 in thewall for cleaning or readjusting the pipe.

We propose to make the collar and clamp of malleable iron, so that theywill be cheap and durable, and the collar may be ornamented in variousways to present a neat and pleasing finish.

Having thus described our invention, we claim as new and desire tosecure by Letters Patentbowed clamp-bar D, having endsd (1, adapted tothe collar-notches a a, a clamp-bar, E, provided with a bolt end, F, anut, G, on bolt F, a clamp-plate, H, supported at its centerat the topof the collar, and a clamp-screw threaded into the collar and adapted toclamp the plate H to the pipe, substantially as herein set forth.

2. The U-shaped clamp-bar D, having arecess, d", in the center of itscross-bar, and provided with lugs d*, in combination with the collar A,the bar E, provided with the screwrod F, and the thumb-screw G,substantially, as herein shown and described.

3. A stove-pipe collar and its clamp comprising a collar, A, providedwith opposite notches and recesses, a a, a bowed clamp-bar, I D, havingends d a, a clamp-bar, E, provided with a bolt end, F, and a nut, G, onsaid bolt, substantially as herein set forth.

4. The combination, with the stovepipe collar A, provided with the lugsJ, ofa clampplate, H, provided with a flange, I, having recess 1;,adapted to lugs J, and the set-screw K, substantially as herein setforth.

5. The combination, with a collar, ofa U- shaped bar secured to thesame, and a bar ad-- justably secured to the U-shaped bar, and ofgreater length than the distance between the arms of the said U-shapedbar, substantially as herein shown and described.
